Detailed Description
As shown in fig. 1 to 5, the blood line puncture needle slippage alarm device for dialysis provided by the present invention comprises an alarm main body 1 and a blood sensor 2. The alarm main body 1 comprises a power supply module 3, the power supply module 3 is connected with the blood sensor 2, and is also connected with a venous line sensor 4 and an arterial line sensor 5; the venous pipeline sensor 4 is connected with a venous pipeline alarm module 6; the arterial pipeline sensor 5 is connected with an arterial pipeline alarm module 7. In addition, the alarm body 1 further comprises a control module 8, and the control module 8 is connected between the blood sensor 2 and the blood alarm module 9. The control module 8 includes a voltage comparator 81 and an operational amplifier 82. The power module 3 is connected to a power switch 31 for controlling the whole circuit to be turned on and off. The power module is also connected with a power indicator lamp 32 and a protective resistor 33.
The blood sensor 2 includes a blood alarm lamp 21 and a blood buzzer 22. The blood sensor 2 is a contact sensor, namely two polymer conductive wires 24 are respectively connected with the positive electrode and the negative electrode of a power circuit, are uniformly distributed in two flaky soft moisture absorption materials 26 in a rectangular layered manner, and the skin-sticking surface of each flaky soft moisture absorption material is provided with an adhesive layer which can be tightly adhered to the skin and is connected with the alarm main body 1 through a special lead 23. The two conductive wires are insulated in a liquid-free state, when blood is immersed, the conductive wires conduct electricity, then the positive electrode and the negative electrode are conducted, and after the circuit is communicated, the blood sensor 2 is started to give an audible and visual alarm.
